STATEN ISLAND, N.Y. - John Catsimatidis, meanwhile, continues to stake out his Island territory. On June 18, Catsimatidis will host a performance of “The Little Flower,” the one-man show about Mayor Fiorello LaGuardia starring Tony Lo Bianco, at Snug Harbor Cultural Center in Livingston.

There’s a little bit of irony here: LaGuardia, a Republican who ran as a “fusion” candidate with support across party lines, was a hero of Rudolph Giuliani’s. Giuliani, of course, is backing his former deputy, Lhota, in the GOP race.

Set to join Catsimatidis at the event are his Island GOP supporters, including former Rep. Vito Fossella. And among those helping Catsimatidis stage the event is Sherry Diamond, a former top aide to Fossella.

The GOP mayoral primary has borough Republican power on both sides.

Lhota has the endorsement of the party organization, as well as backing of Rep. Michael Grimm, Councilmen James Oddo and Vincent Ignizio, and Assemblyman Joe Borelli.

Catsimatidis has Fossella in his corner, as well as state Sen. Andrew Lanza, Assemblywoman Nicole Malliotakis, former GOP chairs Leticia Remauro and Mary Reilly, and former Assemblyman Matt Mirones.

It will be interesting to see who will best mobilize their troops on Primary Day. 
